Simon Sturgis has been
studying carbon emissions in the building industry for the last 8
or 9 years. He uses his experience to look at the scenarios of when
it might be best to demolish and rebuild, or whether retrofit might
be a better option. He also explains how new buildings should be
created with their ‘circular economy’ in mind.

Andrew Michler has been living off grid in the Colorado Rocky Mountains for over 20 years. He has had a long interest in sustainable design and as well as completing a book about how sustainable architecture around the world responds to its conditions, he has also created Colorado’s first certified Passivhaus home.

Potton have a history of serving the self build market and are currently building a Passivhaus show home. They are making the details of the build available through their Self Build Live events and are running courses through their Self Build Academy to help people through the self build journey. Paul Newman explains why they’re doing this, and also what lessons they’ve learned from the construction of their Passivhaus show house.

Like Ben Adam-Smith, Michelle is a podcaster who is keen to build her own home and is sharing the information she learns along the way with her audience. In this episode she and Ben discuss how some of the challenges of the self build market compare in the UK and the US, and also some of the best things about their respective housing industries.
